Find the y-intercept for the parabola defined by
this equation:
y=x^2+ 2x – 8

Answer:

Step-by-step explanation:

No. of people who took the test = 50

No. of women who took the test = 18

Therefore, no. of men who took the test = 50 - 18 = 32

No. of men who did not pass the test = 1/4 × 32 = 8

No. of men who passed = 32 - 8 =24

The no. of men who passed is 8 more than the no. of women who passed Therefore, the no. of women who passed = 24 - 8 = 16

No. of women who failed = 18 - 16 = 2

Total no. of people who passed = 24 + 16 = 40

Total no. of people that didnt pass = 2 + 8 = 10

Therefore probability that they passed = 50/40 = 1.25

Hope this help : ) . Have a nice day !

Answer:  The probability is  0.8

Step-by-step explanation:

Total who took the test = 50

Women who took the test = 18

50 - 18 = 32  is the number of men

32/4 = 8    men who did not pass

Men who passed = 32 - 8 =24

To find the number of women who passed :  24 - 8 = 16

Total  of people who passed = 24 + 16 = 40

Number who passed out of total people  = 40/50   Converted ro decimal: 0.8

So the probability of randomly selecting a person who passed is 0.8

Answer:

multiplication property of equality

Step-by-step explanation:

Since we are multiplying by the same amount on each side, we are using the multiplication property of equality

Answer: Multiplication Property of Equality

Step-by-step explanation:

This property states that while simplifying an expression, you can multiply both sides of the equation by any number, and it will stay true.  This property is useful here, because multiplying a fraction by its reciprocal = 1, so the expression would become 1x=-128.

Answer:

Hey there!

Answer:

B. 3x + 4 ft.

Step-by-step explanation:

Remember that:

Perimeter of a rectangle: P = 2l + 2w

Given:

P = 8x + 8

w = x.

Plug the given information into the equation:

8x + 8 = 2l + 2x

Subtract 2x from both sides:

6x + 8 = 2l

Divide both sides by 2:

(6x + 8)/2 = 2l/2

3x + 4 = l.

Therefore, the length of the garden is:

l = 3x + 4 ft.

Answer:

y = 3x - 5

Step-by-step explanation:

Slope Formula: [tex]m = \frac{y2-y1}{x2-x1}[/tex]

Slope-Intercept Form: y = mx + b

Step 1: Find slope

m = (-2 - 1)/(1 - 2)

m = 3

Step 2: Find b

y = 3x + b

-2 = 3(1) + b

-2 = 3 + b

b = -5

Step 3: Rewrite linear equation

y = 3x - 5

Step 4: Graph using graphing calc

We know that the perimeter is at most 57 feet. We will call the length of each side with the variable 'x'. Each side is the same since it's an equilateral triangle.

The perimeter of the triangle is defined as '3x' because 3 times the side length of an equilateral triangle is its perimeter.

Since the perimeter is at most 57 feet, it can't be more than that. Therefore, we get the inequality 3x≤57.

This inequality is the same as saying the perimeter is less than or equal to 57 feet.

Now we solve.

3x≤57

Isolate 'x': 3x/3≤57/3

0<x≤19 is our answer.

The reason there is a "0<" added is because the side of a triangle can't be less than 0, that would be impossible.

Step-by-step explanation:

It is given that,

Number of red markers = 3

Number of blue markers = 5

Number of yellow markers = 3

Number of black markers = 4

Total markers = 3 + 5 + 3 + 4 = 15

Probability of getting a black marker is

[tex]P(Black)=\dfrac{\text{Number of black markers}}{\text{Total markers}}[/tex]

[tex]P(Black)=\dfrac{4}{15}[/tex]

Probability of choosing two black markers if the first marker is put back before the second is drawn, is

Required probability [tex]=P(Black)\times P(Black)[/tex]  

                      [tex]=\dfrac{4}{15}\times \dfrac{4}{15}[/tex]

                      [tex]=\dfrac{16}{225}[/tex]

Therefore, the  probability of choosing two black markers if the first marker is put back before the second is drawn, is [tex]\dfrac{16}{225}[/tex].

C--254 miles behind truck B

Answer:

(10, 14)

Step-by-step explanation:

To solve this system let's use substitution:

Solve the first equation for x, obtaining x = 24 - y, and then substitute 24 - y for x in the second equation:

3(24 - y) + 5y = 100

Performing the indicated multiplication, we get:

72 - 3y + 5y = 100

Combining like terms results in 72 - 100 = -2y, or -28 = -2y

Thus, y must be 14.

If y = 14, then the first equation tells us that x = 10.

Check:  Is this true?  3(10) + 5(14) = 100  YES

The solution is (10, 14).

Answer:

There are 360 such numbers.

Step-by-step explanation:

The number of 6-digit numbers, formed using each digit from 1 to 6 excactly once, means we can have numbers like

123456, 123465, 123546,123564,.... 654321

The number of such numbers is given by 6! because we have a choice of 6 numbers for the first digit, 5 left for the next, ... until the last digit has only one choice.

6! = 6*5*4*3*2*1 = 720

We know that 1+2+3+4+5+6 = 21 is divisible by three, so all 720 numbers are divisible by 3.

However, to be divisible by six, we need a number divisible by three AND divisible by two.

Thus, out of the 720 numbers, we need count only the even numbers, which are exact half of the 720, or 360.

Therefore there are 360 6-digit numbers, formed using each digit from 1 to 6 exactly once, are divisible by 6.

Answer:

360 numbers

Step-by-step explanation:

6-digit  numbers => the numbers have the form abcdef

f  3 values, f = {2; 4; 6}

a  5 values;   b  4 values, c  3 values,  d   2 values,   e  one value,

=> 5 * 4 * 3 * 2 * 1 * 3 = 360 numbers

Answer:

The midpoint is (8,9.5)

Step-by-step explanation:

The midpoint is found by averaging the x coordinates and the y coordinates

x = (x1+x2)/2     y = (y1+y2)/2

x = (13+3)/2 = 16/2 = 8

y = (5+14)/2 = 19/2 = 9.5

The midpoint is (8,9.5)

The amount raised by Akeelah is x, by Barika is x- 2.60, and by James is 2x- 5.20.

If we analyze it via steps,

We first take the value we know, that is the amount raised by Akeelah that is x. So if Barika is 2.60 less than Akeelah we will numerically express the equation as x-2.60.

Then we look at the amount raised by James it says that it is twice as much as Barika, we numerically express that as

2(x- 2.60) = (2.x) - (2 . 2.60) = 2x -5.20 (simpler form)

If we want to find out the amount we can even do so by adding the amount raised by Barika, Akeelah, and James. We numerically express that as x + (x-2.60) + (2x-5.20) . This equation will be equal to the total value given as the amount raised by all three which is $76.23.

So, By the Problem,

x + (x-2.60) + (2x-5.20) = 76.23

=> 4x - 7.80 = 76.23

=> 4x = 68.43

=> x = 68.43/4

=> x = 17.11

Therefore, Akeelah raised x = $17.11

Barika raised x-2.60 = $14.51

James raised 2x -5.20 = $29.02

Answer:

-25

Step-by-step explanation:

Essentially, y is your output and x is your input.

Here's your base equation: y = 2x + 5

Knowing the information above, let's plug it in:

-45 = 2x + 5

(Subtract 5 from both sides)

-50 = 2x

(Divide both sides by 2 to isolate x)

-25 = x

And there you go.

Answer:

input is -25

Step-by-step explanation:

y = 2x + 5

The output is -45 which is y

-45 = 2x + 5

Subtract 5 from each side

-45-5 = 2x

-50 = 2x

Divide each side by 2

-50/2 = 2x/2

-25 = x

The equation of the graph of inequality is y > 4x + 2.

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥.If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line.

According to the question

Graph show the inequality  

As graph is having a doted line

as we know

The boundary line is dashed for > and <  in graph of an inequality

i.e

inequality will have either > or <  

Now ,

As we know according to the graph of an inequality

If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line.

As area is shaded above the line

i.e it will have

>sign  in inequality

As per options

only option B is valid   which have  > sign in inequality .

Therefore,

the equation of the graph of inequality is y > 4x + 2.

Hence, the equation of the graph of inequality is y > 4x + 2.
